Predict the output of following program.#include<iostream> using namespace std; class Point {    int x; public:    Point(int x) { this->x = x; }    Point(const Point p) { x = p.x;}    int getX() { return x; } }; int main() {   Point p1(10);   Point p2 = p1;   cout << p2.getX();   return 0; }

Predict the output of following program.

#include<iostream>
using namespace std;
class Point {
    int x;
public:
    Point(int x) { this->x = x; }
    Point(const Point p) { x = p.x;}
    int getX() { return x; }
};
int main()
{
   Point p1(10);
   Point p2 = p1;
   cout << p2.getX();
   return 0;
}
